No particular issues so far, as long as I don't open the sqlite file to do random stuff with the notepad, but the main reason I want it back to default is that I don't want to deal with potential corrupted files or annoying stuffs in the future (if it can cause it).

Nah you should be fine mate, changing the default program shouldn’t cause you any trouble as the processes that interact with it can still do so. As long as the extension doesn’t change, it may just be a little annoyance for you.
